I recently bought 2 Glock 43/48 frames and built 2 43x’s. They both have aftermarket barrels and slides but they are quality made parts. They both have feeding issues from the start.
The one will fire the first round but will never load a 2nd. Not once has it performed a complete cycle.
I tried to figure out the problem so i first looked at each issue that could be the cause.
1- im not limp wristing
2- nothing wrong with the mags at all and have tried several mags
3- not the ammo. Its quality new Winchester white box and Remington 115gr RN
4- guide rod. This is what im thinking the issue may be. The factory weight is 17lbs and i think it needs a 15 or maybe a 13lb spring. I bought a 15 and 13 pound guide rods and gotta get to the range soon to see if this fixes the problem
Has anyone here ever had a issue like this with a 43x and if so what fixed it?
Thanks guys
The first 43 I bought I was not happy with because the frame is just too small for me. So I bought a brand new takeoff 43X-48 frame off gunbroker, slapped the 43 slide on it creating a fake 43X out of two Glock guns, and before even testing it I brought it to a class where I fired 450 rounds out of the gun without one failure. That’s how much faith I have in the platform.
I actually agree with you 100% that when Glocks are changed from OEM parts to aftermarket is when there are problems. Ive never had a single issue with 100% factory Glocks.
My 2 43s were never complete factory guns. They were just 2 stripped frames i bought and i built them up using aftermarket parts but looking back i should have bougnt Glock 43x factory slides and barrels instead of aftermarket.
Im hoping the new lighter guide rods fix the issue and if not im gonna buy OEM complete 43x slides for them.
I actually did the same thing sort of. I bougnt a 80% regular 43 frame to build but it just felt too small in my hands and i found a great deal on 2 43/48 OEM stripped frames so i bought those and the fit and feel of the 43/48 frame is so much better then the 43. Also my main carry gun since 2004 has been a G19 so the 43x was easy to like since its basically a thinner 19 frame
Yes I did on one of them but not the one that doesnt fully cycle.
It maually cycles rounds just fine but wont cycle after firing a round. With tje 17lb guide rob the slide goes back just far enough to load a new round from the mag but when i installed the new 13lb spring it now goes back just a little further as it should and I think its gonna cycle properly or im hoping so!
Do you think a optic can play a role it this issue cause the other one has a optic and it cycles for a few roumds and then has a FTFeed like the 1st 43x
I think it’s a non-stock Glock problem. Stock Glocks (with few/older exceptions, like some old G22’s ISP had for example) tend to work with good ammo and mags, including with optics attached.
I agree 100% as I have several Factory Glocks that I don’t think I’ve ever had a malfunction with and now I can’t even get these two to run right from the start so I’ll never getting aftermarket parts ever again so it was a valuable or an expensive lesson learned
I had a failures to cycle after I had a gunsmith put a Holosun optic on my 43x . It was brand new,hadn’t been fired. Come to find out, the gunsmith put the factory screws back in instead of using the Holosun supplied screws, one of which is 2mm shorter so as not to interfere with the spring directly below it inside the slide. I replaced the screw with the Holosun one and no more failures.
I have a serious Glock problem. This problem has been an ongoing thing for years. I’m amazed that this glaring issue has not come up more often because I have been experiencing it for many years. Every since my 1st Glock, I have not been able to afford the necessary number of Glocks to fill my needs. Maybe it’s money, or maybe my wife has become “Glock resistant”. I see this as a very serious Glock problem.
I recently returned my Glock 43 to the factory for repairs. The firing pin was hitting the primer on the lower left and it would misfire every 10 rounds or so. I had several 3rd party accessories on the gun including a match barrel and slide lock. When i received it back all the 3rd party parts were replaced by factory OEM parts. It now fires flawlessly with all kinds of ammo. I now CCW this gun.
I’ve seen that problem several times with aftermarket barrels that do not line up the chamber with the firing pin correctly. Because of that my Glocks will never see an aftermarket barrel.
My wife had gotten a “pretty” 43x at a gun show.
It is our first Glock. Has not had any real problems.
I am not a fan of the polymer mags. They go in real tight, and don’t seem to drop out cleanly (alot of resistance and don’t just drop).
Just our experience.
It really seems to be a very big agreement to just leave factory Glocks alone or your just asking for problems.
Now mine wasnt a complete firearm it was just a OEM Glock frame 43/48 and i bougnt aftermarket parts to finish it. I have several Glocks from yeats back and all OEM and never had any isues.
These 2 new 43x both had issues from day 1.
So major lesson learned by me
I will only buy complete finished Glocks from now on!
The ONLY aftermarket parts I’ll ever put in my Glocks are 3.5# Ghost Connectors, Shield Arms magazines and their metal magazine catch, and HiViz fiber optic front sighs. I have tested all these mods extensively!!!
I also polish all the steel internals surfaces mirror bright and lightly grease with high temp bearing grease. That gives me an improved capacity Glock with better sights and a perfect glass smooth 3.5-3.8lb trigger. THAT is perfect turn in a carry gun
On my personal Glocks, more rounds in every training session than most folks fire in a year. I also have those mods in 7 Glocks currently all running at 100% and three of them are loaner guns for my students so they get run a lot with little or sometimes no maintenance.
BTW one is what I lovingly call my Frankenglock. A 43 which I bought for my wife and then acquired a new 43X/48 new OEM frame so I switch the slide back and forth between the 43 and the 43X frame with zero issues.
I hear that more often than you think, not trying to come off wrong, do you have a definitive number of how many rounds your firing in a session, or could you eloborate on how many rounds fired to date on those.
